It would save a lot of time for many people if lightroom would allow the user to customize the place of every slider and even make their own tabs with just the tools they use 95% of the time.

For example, I use upright on about 50 images / day. Many times, especially composite images, need some cropping/scaling and I then have to switch to another panel to do that( > manual > + scale). Just a few clicks but would be really sweet to have the two buttons side by side...

If you have used zbrush for example, the customization is really sweet.
